Silicon carbide (SiC) is a hard, chemically inert material widely used as both an abrasive and ceramic component in high endurance products. Available in various grain sizes and binder formats with differing purity levels and densities, SiC can be found everywhere from industrial applications to consumer goods manufacturing facilities. SiC was first mass produced commercially by Edward Goodrich Acheson in 1891 through his Acheson process after discovering what appeared to be moissanite-like black crystals while heating an electrically heated solution of clay and powdered coke. The chemical process Silicon Carbide (SiC) is an extremely hard material with unique ceramic and semiconductor properties, which makes it a fantastic option for high-temperature …

Silicon carbide is an versatile compound with numerous applications in numerous industries such as resistance heating, flame igniters and electronic components. Due to its composition and manufacturing process, silicon carbide can act both as an insulator or conductor depending on its composition and fabrication process. With such diverse properties it has become an invaluable asset in these areas of practice. Manufacturers can tailor its electrical conductivity by doping it with nitrogen, phosphorus, beryllium, aluminum and gallium to produce either n-type or p-type semiconductors. Furthermore, its high thermal conductivity makes it a useful material for heat exchange applications. Properties Silicon carbide, commonly referred to as SiC, is a hard and durable …
